Any Tora will handle your weight. I'm 240 and have ridden a Tora Solo Air for years. The advantages of the Air are primarily that you can set the optimal spring rate for your weight using a shock pump and adjust it at will. To adjust spring rate on a coil sprung fork, you have to buy a new coil spring and install it. The air fork will be somewhat lighter. OTOH, some people prefer the feel of coil springs.

I'm 235 (down from 250) pounds and I have had very good results with the 302 solo air on my Hi Fi. It's a 120 mm fork and I don't need to run anywhere near the air pressure that is suggested for my weight and it works fine. I'n not sure I'd want a coil spring fork unless I was certain that I needed the real big hit performance. Todays crop of air forks are awesome.
